Description

Coal gasifier for coal gasification production

Technical Field

The invention relates to the field of coal gasification production equipment, in particular to a coal gasification furnace for coal gasification production.

Background

Coal gasification refers to the process of converting solid fuels such as coal, coke, semi-coke, etc. into gas products and a small amount of residues by reacting with a gasification agent under the conditions of high temperature, normal pressure or pressurization. The gasifying agent is mainly water vapor, air (or oxygen) or their mixture, and the gasifying reaction includes a series of homogeneous and heterogeneous chemical reactions. The obtained gas product has different compositions according to the types of the raw materials, namely coal quality and gasifying agents and different gasification processes, and can be divided into air gas, semi-water gas, water gas and the like. The coal gasification process can be used for producing fuel gas, which is used as industrial kiln gas and city gas, and also used for producing synthesis gas, which is used as raw material for synthesizing ammonia, methanol and liquid fuel. Is one of the important processes in coal chemical industry. And the coal gasifier is the main equipment for coal gasification. There are various gasification methods according to the properties of coal and the different requirements for coal gas, and the corresponding gasification equipment includes fixed bed (moving bed) gasification furnace (such as coal gasification furnace, lurgi coal gasification furnace, etc.), fluidized bed (boiling bed) gasification furnace (such as winkler coal gasification furnace, etc.), entrained flow bed coal gasification furnace (such as K-T coal gasification furnace, Texaco coal gasification furnace, etc.)

Because the coal needs certain time in the coal gasifier reaction, and then need control the volume that the coal got into the coal gasifier, and current coal gasifier lacks the device of control coal input, and then lead to a large amount of coals to pile up in the coal separator, and then lead to a large amount of coals to get into the coal gasifier in the short time, and then lead to the unable abundant reaction in the coal gasifier again, and then caused the waste of resource, be mingled with a large amount of coal ashes in the coal gas that coal gasifier produced simultaneously, and present washing cooler lacks filter equipment and then causes partial coal ash to discharge along with the coal gas.
